Mumon's Comment: Ummon fed Tozan good Zen food. If Tozan can
digest it, Ummon may add another member to his family.

In the evening Tozan swam around in a sea of good and bad, but at dawn
Ummon crushed his nut shell. After all, he wasn't so smart.

Now, I want to ask: Did Tozan deserve the three blows? If you say
yes, not only Tozan but every one of you deserves them. If you say
no, Ummon is speaking a lie. If you answer this question clearly, you
can eat the same food as Tozan.

The lioness teaches her cubs roughly;
The cubs jump and she knocks them down.
When Ummon saw Tozan his first arrow was light;
His second arrow shot deep.
